hipped, heavy-bodied, and perhaps semi-aquatic in habit. Its

The bones of the forelimbs are short and disproportionately 

 heavy, while those of the hind limbs are short and relatively 

 light. The scapula varies noticeably from the general pro- 

 boscidean type. The prescapula seems to be reduced to a 

 remnant in the lower half and to a mere ridge in the upper. 

 The postscapula and mesoscapula are correspondingly devel- 

 oped. The mesoscapula extends as a stout, erect ridge to the 

 suprascapular border. The humerus, radius and ulna, carpals, 

 and phalangeals are noticeably short and extremely heavy.
